This cylindrical bottle has an angular shoulder and a short flared neck. The decoration consists of ridged vertical ribs twisted slightly counter- clockwise against the mould. The decoration on this vessel was created in a mold similar to one of the only two surviving molds – namely, a bronze dipped mold decorated with small lozenge-shaped bosses now in the Corning Museum of Glass. The vertical ribs were twisted by the glassmaker to create the final ridge decoration in the mold. Both the shape of this vessel and the type of opening seem to point to an earlu period of Islamic glass production, probably before the eleventh century and more likely in the tenth.
Vessels of this kind were believed to have held an oily substance, and the decoration was designed to make then easier to hold.Login to view price
